Abstract

The present invention relates specifically to manufacturing method of puffed and granulated protein feed for ox and sheep by utilization of industrial agricultural, environmental waste products. One or several kinds of the above waste products such as straws, blighted shells, stems and leaves of plant, feed processing by-products, animal wastes are mixed evenly with minerals, trace elements, coarse grain powder according to specific ratio, and the puffed, granulated protein for ox and sheep is manufactured by procedures of puffing and pelletizing drying, cooling, screening and separating. Meanwhile, there are no addition of chemically synthesized growing accelerant, binders, condiment etc., thus the real green environmental feed is manufactured.

Description

Manufacture method of a kind of puffed granular protein feed of ox and sheep and products thereof

The present invention relates to feed and feed processing technology field, refer in particular to a kind of industrial or agricultural, environment discarded object of utilizing and produce manufacture method of puffed granular protein feed of ox and sheep and products thereof.

Along with reform and opening-up and social development, China's living standards of the people improve constantly, and the kind that the "shopping basket' project is provided requires also more and more to tend to diversification, and the demand of animal protein increases substantially, and has promoted the development of aquaculture.But China has a large population and a few land, and the high-quality feed shortage becomes " bottleneck " of restriction aquaculture development.Comprehensive utilization industrial or agricultural, environment discarded object are produced puffed granular protein feed of ox and sheep, not only for the development aquaculture creates conditions, also can alleviate the pollution of every profession and trade to environment.

The object of the present invention is to provide a kind of industrial or agricultural environment discarded object that utilizes to produce protein content height, cheap puffed granular protein feed of ox and sheep.

The process that another object of the present invention is to produce feed is not added the growth promoter of chemical synthesis, adhesive, flavor enhancement etc., makes real " environmental type feed ".

The object of the present invention is achieved like this: with a kind of or several materials in the industrial or agricultural environment discarded objects such as stalk, not plump shell, plant base of leaf, food industry accessory substance, animal waste after the biological treatment of physics or physics, press special ratios and functional additive is composite, make puffed granular protein feed of ox and sheep by operations such as expanded granulations, concrete steps are as follows:

1. a kind of in the industrial or agricultural environment discarded objects such as stalk, not plump shell, plant base of leaf, food industry accessory substance, animal waste or several are removed out of use impurity and putrid and deteriorated composition, pulverize or pulverize and add biochemical treatment, sieve and get granularity＜5mm powder;

2. according to each growth period demand of cattle and sheep, select a kind of in mineral matter, trace element, vitamin, amino acid, the urea or several and coarse grain powder (1-50) by weight: (99-50) mixing is made functional additive;

With 1,2 by weight (30-95): (70-5) mixing is made compound;

4. compound is extruded by bulking machine, and drying, cooling, screening operation are made puffed granular protein feed of ox and sheep again.

Described stalk is straw, Wheat Straw, oat straw, beanstalk, millet straw etc.; Not plump shell is rice husk, big wheat husk, wheat shell, sorghum husk, peanut shell, corncob, pone leaf etc.; The plant base of leaf is trees cladoptosis leaf, weeds, reed, pasture and water, algae, duckweed etc.; The food industry accessory substance is the poor liquid of the poor slag of industry such as system wine, vinegar, soy sauce, monosodium glutamate, food coloring, the pulp of tinned fruit factory, Soft Drinks Plant, fruit wine factory, fruit stone, pericarp, pomace etc., the molasses of sugar industry, maltose, megasse, bagasse etc., the slurries of the soybean residue of bean product and starch processing industry, granulated slag, system starch and residue etc.; Animal waste is the internal organ after chicken, duck, dove, dog etc. are butchered, assorted bone, fur, watery blood, gastric content, fowl and animal excrement etc.

Described biological treatment be stalk, not plump shell, plant base of leaf, food industry accessory substance under the effect of bioengineered strain (Trichoderma, Aspergillus, basidiomycetes etc.), carry out the biochemical reaction of a series of complexity.

Described mineral matter, trace element, vitamin, amino acid are egg-shell meal, oyster shell whiting, agstone, rock phosphate powder, sodium chloride, calcium phosphate, magnesia, ferrous sulfate, KI, zeolite, vitamin, methionine, cystine etc.

Described coarse grain powder is corn flour, sorghum flour, wheat bran, rice bran.

Described bulking machine is single screw extruding puffing machine or twin-screw extruding puffing machine.

Described drying process is handled for the drying of carrying out pellet with a kind of or several devices in revolving drier, tray dryer, vibrating fluid bed dryer, belt dryer, infared dryer or the microwave dryer.

Described cooling, of cooling, the screening operation of screening operation for carry out pellet with pneumatic conveyer dryer or fluid-bed dryer.

Major advantage of the present invention:

1. utilize industrial or agricultural, environment discarded object production nutritional labeling height, cheap pellet.

2. extrusion makes starch gelatinization, the increase of soluble dietary fiber amount, protein denaturation, has improved feed digestibility and nutrition

3. biological treatment increases monose, disaccharide and amino acid whose containing in the raw material owing to change stalk, not plump shell, the physics of plant base of leaf, chemical property

Amount also can improve feed digestibility and nutritive value.

4. be the raw material while at the discarded object that utilizes contaminated environment, its production process no longer produces secondary pollution;

5. the process of making feed is not added the growth promoter of chemical synthesis, adhesive, flavor enhancement etc., is real " environmental type feed ".

6. can be according to the cattle and sheep demand in each growth period, the design nutritional labeling is reasonably filled a prescription, and improves the growing of cattle and sheep, gives milk, the breeding level.
